Stream ALPHA SDI is a multi-functional video card, which is able to substitute several devices in a studio at a time. Besides the primary function of graphics overlaying on transmitted digital signal of SDI format or its output for external mixer, the video card may converse analog signal to digital SDI format of video signal and work as frame-grabber and video sequence-grabber.

Stream ALPHA SDI works with 8- and 10-bit serial component SDI input signal and 10-bit - output signal, in accordance with CCIR656 and SMPTE259m instructions. At signal passing through the board all service information is kept, and sound packs may be either kept or replaced depending on the required conditions. In the input signal error check with calculation of checksum under EDH technique is performed. At output, EDH packs are always generated anew according to SMPTE165 instruction.

The board works in external synchronization mode, which is performed on the input video signal. If at the output is only computer graphics, synchronization signal Black burst may be sent to the main input or to optional analog one. At external synchronization absence internal generator is used.

For use of the described devices in combination with external mixer having DSK input (Down Stream Key), key signal output (of alpha channel) is specially designed in analog and digital format. Board setup program allows setting both positive and negative delay of key signal in relation to the output graphics within broad range.

At switching off computer power supply or at BYPASS mode activating inputs and outputs of all devices form a circle through relay, and 75 Оhm load is switched off. During power supply switching off and also initialization no distortions of the transmitted signal take place at the output.

For output of computer graphics the video card memory buffer is used of 720х576 points size for 50 Hz video systems and 720х480 points for 60 Hz systems. Each point has 32-bit representation, 24 bits of which are used for representation of its color (16 mln. shades), and 8 bits – for specification of one of 256 transparency degrees (alpha channel). Although the component of points color of computer graphics has 24 bits in its presentation (8х8х8), at mixing representation of 30 bits (10х10х10) is used, i.e. if the input signal was a 10-bit one, it will remain such at output after mixing.

The memory used for graphics buffer, and also data throughput of PCI bus of modern computers allow to refresh entirely its content in real time without loss of pictures, transmitting uncompressed image (32 bit/pixel) together with the sound component.

Video card Stream ALPHA SDI besides the digital serial input is also equipped with analog inputs - YUV/RGB, S-Video and a composite input. It also may generate analog signals YUV/RGB regardless of input used at the output simultaneously with SDI signal.

For generation of signals at analog outputs 10-bit digital to analog converter with fourfold oversampling is used. It allows obtaining of their HF noise total filtration without additional reduction of channel signal output brightness bandwidth.
